RAILWAY-CAB CON'STRUCTION.

Application filed February 15, 192i. Serial No. 693,046.

To all 'whom t may con/oem:

Be itknown that I, ARoYm CAMPBELL, 'a citizen of the United States,residing at' Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in RailWay-CarConstruction, of which the following 'is a full. clear, concise, andexact description, reference being had to the accompanying drawings,forming a part of this specification.

My inventionrrelates to improvements in railway car construction andparticularly to a novel me-thod of forming the walls of railway cars.

An object of the invention is .to construct the walls of railway cars insuch a manner that portions having descriptive characters, indicia,symbols or designating. marks thereon may be made of a large size andsuitably rigidified without detracting from the advertising value of thecharacters or other designatlng marks .inscribed thereon. It is also anobject of my invention to so construct a car wall that a panel havingdesignating markings thereon will stand outwardly from adjacent panelsand thereby, due to its position on the car structure in relation toother 'portions thereof, attract attention to its markings.

Other objects of the invention will more clearly appear from thedescription hereinafter following.

In' the drawings forming a part of this specification, Figure 1 is aside'elevational view of the side door of a raillway box car embodyingmy improved c'ar construction. Figure 2 is a sectional view taken on aline corresponding substantially to line 2-2 of l `igurc 1. Figure 3 isan end elevatlonal view of a box car having my improved car constructionincorporated therein. Figure 4 is a' sectional view taken on a linecorresponding substantially to line 4-4 of Figure 3.

Referring first to Figures 1 and 2 showing my construction as applied tothe side door of a car, -10 indicate the Vertical inargins of the door,11 the upper horizontal margin, 12 the lower horizontal margin.Intermediate the margins, the body of-the door is preferably formed inthree panels,

13 designating the central panel, 14.' the upper panel and 15 the lowerpanel. Said central 'panel 13 occupies a comparatively large area of thedoor space and carrxes a descri tive symbol 16, which is formed yembossing a portion o body of the plate outwardly thereby providing initself a suitable rigidif'ing medium for the door. While the symbo maybe constructed' to present a continuous embossment and form the solerigidifying means for the door or other element of a car wall, it isoften desirable to attain a' greater degree of rigidity than is possibleby using the corrug'ations of the symbol'alone and to this end I utilizea system 'of stifeners and beamsas shown at 17 and 18 respectively. Said`stiffening' beams may be disposed 'wherever necessary to effectcontinuity of reinforcement and, it will be appreciated by those skilledin the art4 t l 1at the number and disposition of the same will varywith each distinctive symbol. In this particular arrangement shown in Fires 1 and 2 the short stifeners 17 efectively ,reinforce the largeembossed area 19 of the preferably the main upper portion of the Shieldand further unite the three rows of lettersy 20 thereby effectingcontinuity of reinforcement between the respective rows. The upperportion of the shield 19 and the lower portion thereof 21 are inslightly different planes and in order to streng'then the*door at thisline against bulging the 'beam 18 extends o ver the stiffeners 17 andbetween the vertu'al stiffemng members 10-10 therebygreatly reducing theunsupported area of door plate. .With such a system of reinforcementdlsposed on the inner face of the door, it will be seen that anunusually large plate maybe uscd for the 'central paneland. the beams,being on'the inner side of the door, will not detract from the fullefl'ect of the display on the door. The dis lay on the door isfurtheremphasized by ing the upper and lower panels away from` thecentral panel. While I have shown only epressonc crosswise beam 18 it isevdent 'that a plurality of such beams may be used and in fact theentire space intermediate the upper tending, crosswise of the car, 102the .lower endl stifliening beam, 103-103 the side sills of the car and104 a portio-n of the roof-of the car. A central panel 105 extendingbetween and secured to the respective Vertical corner posts 100-100 ispreferably' formed of a -sheet metal plate having` a symbol 106 pressedtherein in the form of an embossment and 'in this manner the plate isconsiderably rigidified against bulging. The construction described inconnection with Figures 1 and 2 is also applicable to the endl of thecar and both the upper panel 107 andA4 r lower panel 108 are dishedinwardly. Crosswise of the car the central beam.111 extends on the innerside of the 'end wall between the corner posts 100-100 and is rigidlyunited thereto. The sheet metal panel is w i 'further rigidified bymeans of nailing strips v109 which are disposed a-t intervals againstthe inner face of the central panel. T heend is lined intermediate theupper and lower panels by means of a series of Wooden boards 110 whichalso co-operate With the embossed symbol to stifi'en the end panel.

While I have shown and described certain embodiments'of my improvedrailway car construction, the same are' merely illustrative, and'Ioontemplate all changes and modifications that come Within the scope vofthe claims'ap'pended hereto.

What I claim is: f

1. In a railway car`wa1l, the combination with Vertical reinforcing`marginal members; of a central panel extendi'ng between said members,said panel having a distinctive symbol'thereon; and additional panelsse- 'cured' to the said central panel atthe upper telligence conveying sI in strength giving quahties with the stiffen- 1,szo,114

with Vertical `reinforcing marginal members; of a central panel havingthe parts Within itsmargins corrugated and strengthened with an integralintelligence conveying symbol; a stiffener intersecting various parts ofthe symbolV and efl'ecting continuity of reinforcement therein; and abeam extending between the said reinforcing marginal members, said beambeing disposed onv the inner' side of the centra-lpanel.

4. In a railway car Wall, a Sheet metal plate having the partswithin itsmargins comigated and strengthened with integral intelligence conyeyingcharacters arranged out of the main planeof said plate so as to resistthe bending of the plate on Various cross lines, and additionalstrengthening mea'ns intersecting the said corrugations -for the purposeof effecting continuity of reinforcement between Various'pai'ts-of thesaid characters. w z i I 5. Ina railway car wall, a Sheet metal platevhaving the parts within, its margins corrugated and stren'gthened With-integral intelligence conveying characters arranged out of thel mainplane of said plate so as to reslst the bending of the plate, andstiflenmg means disposed on the inner side of the tinuity ofreinforcement between various characters.

6. In a railway car Wall, an element en'- plate, said stifl'ening meansefl'ecting contering into 'the construction thereof; saidelementcomprising a metallic member having incorpora-ted within themargins thereof intelligence conveying symbols on the outer side of thewall and stifi'ening. means on the inner side of -the said wall, 'saidinbols (zo-Operating ing means on the inner side ofl the wall.

In wit-ness that I claim the foregoing I have hereunto subscribed myname this '13th day of February-r1924.
